(Redirected) Brief screen freezes on XPS12

I need help. I have searched everywhere and have tried several things but my screen freezes for a short time (5 to 10 secs typically) every few minutes.

I have:

- upgraded my Cypress touchpad software to latest as per Dell (2.5.1.72)

- reinstalled my mouse software (running Windows 10 Microsoft mouse software)

- disabled the touchpad palm rejection

Nothing has worked. This problem began after a Microsoft auto update on Jan 29, 2016 (KB3124262).

System is

XPS 12 9Q23

Windows 10 64 bit - up to date with all auto-updates

Cypress trackpad
